To the shaft of the From the pulley e the rope or cable e passes 50 rudder c, which projects through and into around the pulley e, which latter is loosely the stern of the boat, is secured the yoke 0 mounted on a pin or axle supported in the adapted to be operated by the yoke-lines c, bracket f", arranged on the gunwale of the boat and near the seat to be occupied by the rower. Hence over the pulley e at the end of lever 6, back to a pulley e loosely arranged on the axle of the pulley c and thence to the eye a", projecting from the free end of the oar or lever e, to which eye the said rope or cable 6 is firmly secured. The pulley e is fulcrumed, as at 6 to the car or lever e. Said oar is adjustably arranged by means of the set-screw f to and within the sleeve 6 the downwardly-projecting shaft f of which is swiveled by means of the conical or spherical shaped collar f to the bracket f, secured to and projecting from the gunwale of the boat a. The swivel motion of the shaft f is limited by means of the collar f secured to said shaft, as clearly shown in Fig. 5 of the drawings.

In operation when the handles of the oars or levers e are pulled forward the ropes or cables 6 are operatedthat is to say, are pulled in the direction of the arrows in Fig. 2. The drum b is thus rotated by the uncoiling of said ropes and through its pawl-and ratchet connection operates the shaft 1), which in turn transmits its motion through the beveled gear-wheels b or b to the propellershaft. By means of the treble purchase or luff-tackle e c and e the rope e is given a faster movement than that of the handles of the oars, as will be manifest. Vifhen the handles of the levers or oars e are pushed forward, the spiral spring, which during the uncoiling of the ropes or cables 6 has been uncoiled, returns to its normal position and carries the drum 5 along with it, whereby the said cables or ropes are again coiled or wound upon their respective grooved section-s, as will be manifest.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

propeller-shaft,of a vertically-arranged shaft,

means for transmitting the motion from said vertical shaft to the propeller-shaft, a springcontrolled drum loosely arranged on said vertical shaft, aratchet-wheel slidin gl y mounted on said shaft, a series of spring-controlled pawls arranged on said drum and adapted to engage said ratchet wheel, a rope coiled around said drum and secured thereto with one end, an oaror lever swiveled on said boat, and connected with its outer end to the other end of said rope, and a luff-tackle intermediately arranged between the end of said lever or oar and the drum and having the rope or cable passing through and overthe same, all said parts being arranged, substantially as and for the purposes described.

2. The combination with a boat and the propeller-shaft, of a beveled pinion on the inner end of said propeller-shaft, a verticallyarranged shaft, a beveled gear-wheel on said shaft and meshing with the beveled pinion, a spring-controlled drum loosely arranged on said vertical shaft, a ratchet-wheel slidingly mounted on said shaft, a series of spring-controlled pawls arranged on said drum and adapted to engage said ratchet-wheel, a rope coiled around said drum and secured thereto with one end, an oar or lever swiveled on said boat, and connected with its outer end to the other end of said rope, and a luff-tackle i11- terniediately arranged between the end of said lever or oar and the drum, and having the rope or cable passing through and over the same, all said parts being arranged, substantially as and forthe purposes described.

3. The combination with a boat and the propeller-shaft, of a spring-controlled drum, means for transmitting the motion from said spring-controlled drum to the propeller-shaft, a rope coiled around said drum and secured thereto with one end, an intermediate lufftackle having the rope or cable passing over the same, and an oar or lever swiveled on the boat and having the other end of said rope secured to its outer end, all said parts being arranged, substantially as and for the purposes described.

4. The combination with a boat and the propeller-shaft,of a vertically-arranged sh aft, means for transmitting the motion from the vertical shaft to the propeller-shaft,a spring controlled drum loosely mounted on said vertical shaft, a series of pulleys arranged on the side of the boat, an oar or lever swiveled on said boat, a pulley carried by the outer end of said oar, two pulleys loosely mounted on an axle supported by the boat, and a rope coiled around the drum and secured thereto with one end, and passing over the series of pulleys and secured with its other end to the outer end of the oar or lever, all said parts being arranged, substantially as and for the purposes described.

5. The combination with a boat and the propeller-shaft,of a vertically-arranged shaft, means for transmitting the motion from the vertical shaft to the pro'pellenshaft, a springcontrolled drum loosely mounted on said vertical shaft, a series of pulleys arranged on around the drum and secured thereto with one end and passing over the series of pulleys and secured with its other end to the outer end of the car or lever, and means for reversing the motion of the propeller-shaft, all said parts being arranged, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of December, 1896'.
